sux. I wish you the best bud!

What are you looking to pick up next?

 

Radical make a nice track car. I believe is can be driven on the street if spec out with lights, turn signals, wipers, etc.

 

 

I wouldn't mind a Juno TR...

 

^MSRP?

 

$63,000

 

Anyone know what max percentage of leakdown should be? 20%?

 

I've always heard under 10%. We hold the motors we build at 928 to under 5% though for our race car.

 

Ive heard 10%

 

My z tested to 7% on my matco tester when I checked it during first tt install (stock engine low miles very cold). Last I checked my built engine it was 8-9% on the same tester (engine lukewarm).... But different testers can vary a few percent... Usually if something is wrong you will see it as one or two cylinders at 10% + worse than the rest

And I think my tester reads on the higher side... Another one I used to use a lot would generally say 3-5 % on stock engines

 

Let's keep our fingers crossed. I will be doing it Thursday with Quadcam!

 

I believe you will have to trailer a Juno TR to the track.

 

Sharif told me anything above 10% deserves some close attention.

For comparison sake, my motor was between 3-5% on 5 cylinders with one cylinder just about at 8%. Motor had 15K boosted miles on it at the time of the leakdown test, car is daily driven. Pistons are 8.5:1 cr Arias .020 over standard duty (ie "the old ones", lol) are installed.

 

I heard 10% variance as well. According to Sharif, my built motor after 4k miles, when I had my coolant scare was:
5 cylinders were 3% and one was 6%, which is pretty great according info that I have read on line.

 

how about.........http://www.radicalsportscars.com/

 

My leakdown on my built motor was 8%

 

Cool!

Are you going to Andrew's new shop? I hear it's really sharp... New lift and all...

Good luck!

 

hope you sort things out larry

I did the leakdown just now and the results are....

1) 5%
2) 14%
3) 18%
4) 3%
5) 8%
6) 3%

So it looks like I need to rebuild the motor! All this after 4000mi. Almost 1500mi of it driving back and forth to shops for work.

 

dude.. that sux ballz. I'm on my 2nd rebuilt engine and might even go 4.2, if this one blows. I feel your pain though.. get something with a factory turbo, maybe.
